A method of producing metal-coated abrasive grain granules suitable for the manufacture of metal bonded diamond tools, by the steps of initially preparing a slurry of metal powder with a solution of an agglomerating binder dissolved in an organic solvent, agitating the slurry to homogenously suspend the metal powder therein, and spraying the slurry using an atomizing nozzle into a fluidized suspension of abrasive grains within a fluid bed granulator to progressively build and dry a uniform spherical coating of the slurry on each individual abrasive grain.
